The Ravens concluded their preseason with a 24-21 loss to the St. Louis Rams in a game that featured none of the team’s starters and extensive work for a number of bubble players fighting for spots on the 53-man roster.

With third-string quarterback Caleb Hanie playing the entire game, it’s difficult to conclude that anything changed dramatically in the competition at wide receiver and tight end where a few spots were still up for grabs. However, the battles for the potential No. 3 running back job and the fourth safety spot featured plenty of action for players projected to be on the bubble.

The Ravens appeared to suffer only one significant injury in Thursday’s game as linebacker D.J. Bryant suffered a significant knee injury at the end of the first half that will likely sideline him for the rest of the season. Though the Randallstown High alum was a long shot to make the 53-man roster, he appeared to be a solid candidate for the practice squad after joining the Ravens in that capacity last year.

My final look at the roster suggests 44 healthy players are locks as the Ravens make final decisions by Saturday. My assessment of the 75 players on the roster lists 16 players on the bubble with at least some chance of making the final roster. Not all bubble players are on equal footing, with certain positions lacking quality depth and others enjoying an abundance of talent.

Though general manager Ozzie Newsome, Harbaugh, and the remainder of the coaching staff and front office are cognizant of the number of players at each position, trying to pinpoint a specific number of wide receivers or linebackers isn’t the most accurate way of projecting the roster. The Ravens will always look carefully at players’ special-teams abilities in addition to what they bring to their specific positional group.

The Ravens must trim the roster to the regular-season number of 53 by 6 p.m. on Saturday, and Harbaugh told reporters following Thursday’s game that some cuts would be made early while others likely wouldn’t come until Saturday.

The numbers in parentheses indicate the total number of players projected to be on the 53-man roster at that given position. Players listed as injured or suspended do not count against the 53-man roster when final cuts are made. Players deemed to be on the bubble are marked with an asterisk.

QUARTERBACKS (2)
IN: Joe Flacco, Tyrod Taylor
OUT: Caleb Hanie, Dayne CristSkinny: The Ravens were wise in keeping Taylor out of harm’s way and allowing Hanie to go the distance. All signs point to Baltimore carrying just two quarterbacks on the 53-man roster for the fourth straight season.

RUNNING BACKS & FULLBACKS (6)
IN: Ray Rice, Bernard Pierce, Vonta Leach, Kyle Juszczyk, *Anthony Allen, *Bobby Rainey
OUT: *Delone CarterSkinny: Some flexibility — or lack of depth — at other positions might allow the Ravens to carry both Allen and Rainey on the roster for the time being. Allen is a standout special-teams player with limited ability at running back while Rainey shows offensive upside but offers little to the special teams other than as a backup returner.

WIDE RECEIVERS (7)
IN: Torrey Smith, Jacoby Jones, Brandon Stokley, Marlon Brown, *Tandon Doss, *Deonte Thompson, *Aaron Mellette
OUT: *LaQuan WilliamsSkinny: Williams saw no time at wide receiver on Thursday night, making it difficult to read where he stands at this point. Brown turned himself into a lock — he won’t make it through waivers to the practice squad — after a strong performance for the second straight game while Doss and Mellette also played well in the preseason finale.

TIGHT ENDS (3)
IN: Ed Dickson, *Dallas Clark, *Billy Bajema
OUT: *Matt Furstenburg, Alex Silvestro
INJURED RESERVE: Dennis Pitta (will be placed on injured reserve with a chance of receiving the designation to return) Skinny: Clark was unimpressive again, but he’s worked with the first-team offense extensively in practices since signing with the Ravens a couple weeks ago. Bajema and Furstenburg did nothing to distinguish themselves, making you think Furstenburg has a better chance of finding his way to the practice squad.

OFFENSIVE LINEMEN (8)
IN: Marshal Yanda, Michael Oher, Bryant McKinnie, Kelechi Osemele, Gino Gradkowski, A.Q. Shipley, Jah Reid, Rick Wagner
OUT: *Jordan Devey, Antoine McClain, Rogers Gaines, J.J. Unga, Reggie Stephens
INJURED: Ryan Jensen (will likely be placed on injured reserve after suffering a broken foot in the first week of camp)Skinny: Devey has had a solid preseason, but it wouldn’t be surprising to see the Ravens add another veteran to bolster their depth with only eight linemen projected to be on the roster at this point. The fact that Gradkowski didn’t play in the preseason finale tells you he has won the starting center job to begin the season with Shipley backing him up.
